Tolkien, Lord of the Rings (LotR), etc.

I don't like how often and how seemingly lightly various characters in The Rings of Power use Morgoth's name in passing, as if they were talking about their neighbors. It demystifies him, takes away his power, makes him less abstract.

In the entirety of The Silmarillion, if I recall correctly, it is uttered in dialogue but a few times by legendary characters such as Fëanor, Húrin and Fingolfin.

I know this sounds like a minor detail, but words have power and I would like to recall that in some of our own legends and myths knowing the name of an adversary granted some power over them. I can't seem to recall exact examples, but perhaps King Arthur's tale? Help me out...

PS: I'm not a RoP hater. :)
